This invention relates to card index apparatus and more especially to a desk leaf index device.

An object of my present invention is to 5 provide a combined card index means and sliding desk leaf whereby to greatly facilitate reference to the index; to provide a disappearing index guide and to provide a simple protecting means serviceable as a writing plane and other purposes.

More particularly, an object is to make available use of the usual desk leaf as a mounting for a card index system.

Numerous other objects, advantages and features of construct-ion and combination, and details of means will be made manifest in the ensuing description of the herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to within the scope, spirit and principle of the invention as it is more directly claimed hereinafter.

Figure 1 is a perspective of an extended index leaf of a desk with a diagrammatic showing of some of the cards mounted therein.

Figure 2 is a cross-section of the leaf; medially broken. I Figure 3 is a perspective of a card for the rack. a

Figure 4; is a perspective of one form of card rack. Y Y Y 1 Figures 5 and 6 are detail sections showing the rack installation.

Figure 7 is a perspective similar to Fig. 1

showing theslide fully extended and the panels pushed forward to uncover the rear group of cards.

I am aware that numerous rack devices have been devised for attachment of demountable index cards 2 and the illustrative adaptation shows the card 2 having spaced eyes 3 which are designed to be slipped onto hooks or bearing pivots 4 paired in axial 46 alignment on a bar 5 of which a large number can be closely spaced parallel in a row with the hooks exposed. The ends of the bars are held in side channels 6 of rack strips 7.

The present device includes a sliding leaf 50" 10 of a desk D whereby the leaf serves as a disappearing support for the cards and can be extended to present the cards for ready access. It will be seen that this structure wholly eliminates apparatus ordinarily mounted 'on the tops of desks or special shelves and taking up space otherwise useful.

The leaf 10 is preferably in the form of a shallow frame providing a shallow chamber preferably closed at the bottom by a thin plate 11 rebated in the bottom of the leaf frame or slide.

Extending longitudinally in the leaf chamber are rack strips 7, above mentioned, whose front ends are held in a rebate 13 and whose rear ends are clinched under a screwed cross-cleatl l; the strips resting on the bottom plate 11.

The position of the card bars 5, in the racks near the bottom of the sliding leaf, 70"

permits the cards 2 on the hooks to be folded down quite flat in the sliding leaf 10 and this can be pulled outward from the desk D to expose the racked cards, which can be tipped up, as seen in Fig. 1, for inspection. 75

If desired, slidable cover panels 16 may be mounted in guides 17 just under the top of the slide 10; these panels being shiftable to cover and uncover different areas of the card racks and forming convenient Writing beds when in covering position in the extended relation of the sliding leaf. Each panel is slightly less than one-half the length of the card chamber so that access to the front' group of cards is had by moving both panels to the rear, or by reverse movement access is had to the rear group.

It will be understood that different types of card racks may be evolved or adapted as desired;

What is claimed is A desk having a sliding leaf comprising a frame, a bottom sheet fastened to the frame a top comprising over and under sliding sections which when extended to opposite extremes close the frame opening, and index card holding means disposed in the frame and which are accessible by adjustment of superadjacent sections together toward the front or toward the back of the leaf as needed.-
